Active collections are those that either are regularly updated, or that are the latest data version of a particular feature representation.

Data Collections From the Past

Webpage content for the following data collections would take a considerable amount of time to update, yet the data are either not considered the most current available, found elsewhere online, superceded, or otherwise inactive. Therefore, the pages have been un-linked and archived. In order to preserve the documentation of these collections, the archived page names are listed in parentheses, and may be found by going to http://www.lib.ncsu.edu/gis/old_files/{page.html}. If you need further assistance, contact Data Services.
